Cass
Information Systems, Inc.
(NASDAQ: CASS),the nation's leading provider of
transportation, energy, telecom and environmental invoice payment and
information services reports that it earned $2.02 per diluted share for
the year ended December 31, 2012, a .5% increase over the $2.01 per
diluted share earned in 2011. Total net income for 2012 was $23.3
million, a 1.3% increase over the $23.0 million earned in 2011.

Cass fourth quarter earnings were $.46 per diluted share, a 4.2%
decrease from the $.48 per diluted share it earned in the same quarter
in 2011. Net income for the period was $5.3 million, or 2.7% less than
the $5.5 million recorded in 2011. A $1.7 million decline in net
investment income was primarily responsible for the lower quarterly
result.

During the fourth quarter the 5.4% volume increase in transportation
transaction volume was fueled by increased activity from both
established and new customers. Conversely, facility expense dollar
volumes declined 3.8% owing to lower pricing for electricity and natural
gas as well as customer turnover. Overall, revenues grew to $26.8
million, a slight increase over the $26.5 million generated in the
year-earlier period.

Operating expenses were up 2.5%, or $476,000, largely due to costs
associated with the continuing ramp-up of the company's new
environmental expense service line acquired last January.

2012 Fiscal Benchmarks

Revenues for the year ended December 31, 2012 were $111.5 million, 4.7%
higher than 2011 revenues of $106.5 million.

Net investment income declined 7.6%, or $3.3 million.

Operating expenses were up 7.1%, or $5.3 million, as Cass invested in
the infrastructure required to expand its new environmental expense
service line.

"As long-time shareholders know, a prolonged period of low interest
rates reduces the earnings contribution of our investable assets,"
commented Eric H. Brunngraber, Cass
president and chief executive officer. "To offset the lingering decline
Cass is experiencing in investment income, our emphasis in 2013 will
remain on investing in initiatives with high potential for profitable
growth in both the markets in which we are established as well as those
we hope to penetrate."

Cash Dividend Declared

On January 21, 2013 the company's board of directors declared a first
quarter dividend of $.18 per share payable March 15, 2013 to
shareholders of record March 5, 2013. Cass has continuously paid
regularly scheduled cash dividends since 1934.
